School proj about reactive programming in JS/ TS

Reactive (Java- / TypeScript)

• Basics idea: asynchronous data streams
• Observers
• Hot vs. cold observables
  • COLD is when your observable creates the producer

      // COLD
      var cold = new Observable((observer) => {
      var producer = new Producer();
      // have observer listen to producer here
      });

  • HOT is when your observable closes over the producer

      // HOT
      var producer = new Producer();
      var hot = new Observable((observer) => {
      // have observer listen to producer here
      });
